You’ve heard of coarse and fine bubbles for aeration in secondary wastewater treatment. Now there are nanobubbles, promising new capabilities.
Unlike fine and coarse bubbles, which emerge from diffusers in a basin bottom and ultimately float to and escape at the surface, nanobubbles largely stay entrained in the wastewater stream and do a variety of good work.
Nanobubbles typically measure about 100 nanometers in diameter, invisible to the eye and 2,500 times smaller than a grain of table salt. For perspective, fine bubbles measure about 2 mm. Nanobubble technology can enhance the performance and productivity of wastewater treatment and industrial processes. Cost-effective and chemical-free,
